Melsoft GX Time delay programming

Bob Paquette · Dec 12, 2003

Having a problem trying to program time delay outputs with melsoft GX developer. I can program the contacts and it accepts those elements labeled with "T" OK but I am doing something wrong when it comes to the timer output. When I try ---[T 3]--- or ---(T 3)--- a help block appears and it is not able to recognize T as a instruction. I have looked through the help list and have not seen any other instructions that would individually serve as a time delay function.
What I am trying to creat in "OLD HAND HELD LOGIC" would look like this:

                                                  Timer

       M110                                           451

 |------]  [-----------------------------------------(     )--|

                                                      K3.0

                                      Reset            Alarm

       451                                 400            435

|------]  [--------------------------------]/[-----------(   )---|

                |

        435     |

|------]  [-----|

What I am trying to do in GX is:



      M110                                                 T3

-------]  [-----------------------------------------------[ 3.0 sec]--





         T3                                 X0             Y5

---------]  [-------------------------------]/[-------------(   )---

                     | 

          Y5         |

----------]  [-------|

ThankS for your help.

Try to use [ ladder] [ /ladder] (no space) to get readable ladder

Timer format in GX ---[T3 K30]-
If timer 0.1 sec it will give you 3 sec delay

Goody · Dec 13, 2003

except it is not square brackets it is round brackets (coil)

---(T3 K39)-

Contr_Conn · Dec 13, 2003

Yes, it will be round coil, sorry... It was a long week...

In Mitsu's PLCs,

K is used for decimal values
H is used for hexadecimal values

When setting buffers and words values they often use H in there manuals examples.

First of all, visit www.meau.com and get programming manual
for your CPU. It is true that you have to use round brackets
or just type:

OUT T20 K30

to setup timer for 3 seconds (resolution is usually 0.1sec but
this is also dependant on CPU and configuration so get the manual).

K30 is 30 so you get 30*0.1sec=3.0sec.
You cannot use values with decimal point after K
("K3.0" is not valid).

To use register as preset for your timer (so you can change it
from HMI for example) type something like this:

OUT T20 D20

and enter timer preset value into D20

OUT T20 D20
and enter timer preset value into D20

Make sure Dxx is in EEPROM or battery backed memory (or they called it LATCH), overvise preset will be 0 every time you restart CPU.

time value changes

I'm using a FX1n- 40mt Mitsubishi PLC I'm using GX developer and I want to change a timer value. It looks like I'm moving K50 Into T201. So I need to change K50's value For the life of me I can't find where to do that.

K50 is a constant, not a variable. K50 = 5 seconds.

To change the timer you have to change this constant to say K100 for 10 seconds.
